Unozivei Nezvedhayi dzeSulfur(2)?

breed

Mhando huru yedhayi dzesarufa ndeyesarufa nhema (CI sulfur dema 1). Inogadzirwa ne hydrolyzing 2, 4-dinitrochlorobenzene uye sodium hydroxide solution mu sodium dinitrophenol solution inenge yave kufashaira, wozopisa nekuvira nesodium polysulfide solution pane imwe molecular ratio, uye kuderedza uye sulfurizing reaction pasi pekumanikidzwa kana kusamanikidzwa. Mushure mokunge sulfurization reaction yapera, inoomeswa zvakananga ne-roller dryer kuti iwane dhayi yepakutanga. Inobva yasanganiswa kuita dhayi dzekutengesa. Munguva yevulcanization, iyo molecular ratio ye sodium phenol uye sodium polysulfide, iyo x (kureva, sulfur index) mu sodium polysulfide Na2Sx uye tembiricha yekuita zvakasiyana, kuitira kuti mwenje weruvara rwesarufa dema chigadzirwa ive nemusiyano wegirinhi mwenje, girinhi. chiedza chitsvuku uye chiedza chitsvuku. Kukanganisa kukuru kwesarufa yakasviba dhayi chiitiko chebrittle cloth. Izvi zvinodaro nekuti iyo sulfide dema molecule ine inoshanda sarufa muchimiro che polysulfide cheni. Izvi zvakaumbwa nesarufa hazvina kugadzikana, uye kana dhayi ichipisa kana kuiswa mumhepo inopisa uye ine unyoro, zviri nyore kuisa oxidize kune sulfuric acid, zvichiita kuti brittleness yemucheka wekotoni. Mumakore achangopfuura, nekuvandudza kugadzirwa kwesarufa dema, yakajairika sarufa dema inotonhodzwa kusvika 100 ℃ mushure mekugadzirwa, uye formaldehyde uye monochloroacetic acid inowedzerwa kudzikamisa isingagadzike sarufa mudhayi, uye anti-brittle sulfur dema. kudhayiwa kunogadzirwa.

Shandisa

Dhayi dzesarufa dzinoshandiswa kuderedzwa kuita leucosome inonyungudika nemvura ine sodium sulfide kana inishuwarenzi poda, yobva yachinjwa kudzokera kuchinhu chepakutanga chisina kunyungudika mushure mekubatwa nedhayi kuburikidza neoxidation kana zvimwe zvinokonzeresa, kuitira kuti dhayi igadziriswe padhayi. .

Shandisa

Dhayi dzesarufa dzinoshandiswa zvakanyanya mukudhayiwa kweselulosi fiber, inonyanya kushandiswa mushinda, maumbirwo uye mamwe machira emaindasitiri nemachira anorema. Mhando dzinonyanya kushandiswa iSulfur Yuan, sulfur blue,

Reductive solution

(1) Zvivakwa zvezvinoderedza vamiririri

1. Zvinhu zveNa2S

(1) Iyo inozivikanwawo sealkali sulfide, zita rinozivikanwa rinonhuwa alkali, iyo inoshanda yeindasitiri alkali sulfide inowanzoita 50%, uye chitarisiko chine yellowish-brown chakasimba. Iyo inoderedza mumiriri, asiwo yakasimba alkali mumiriri, yakagadzikana zvinhu. Iko kuderedza simba re sodium sulfide yakaderera pane yehupfu yeinishuwarenzi, iyo alkalinity yakaderera pane caustic soda uye yakakura kudarika soda ash, uye ine corrosion yakasimba paganda.

(2) Sodium sulfide hydrolysis kuNaHS, NaHS pakuderedza dhayi, zvinogona kuonekwa kuti sodium sulfide kuderedza simba inoenderana nehydrolysis yayo.

(3) Sodium sulfide inogadzira gasi reH2S parinosangana neasidhi, saka kungwarira kunofanira kutorwa kudzivirira kuti isaiswa pamwe chete neasidhi.

(4) Sodium sulfide kuratidzwa mumhepo kunotora mvura, C02, 02, nezvimwewo, kuitira kuti kuumbwa kunobudirira kunoderera uye zvishoma nezvishoma kukundikana. Nokudaro, inofanira kuiswa chisimbiso kana ichichengetwa, uye kuumbwa kwayo kunofanira kuongororwa kana isingashandisi zvakare kwenguva yakareba.

(5) Sodium sulfide solution haifaniri kuva yakareba, kana zvisina kudaro ichave yakasvibiswa nemhepo uye kuderedza kushanda kwayo.
